ROLLER DOORLATCH Filed June 1, 1935 2 Sheets-Sheet 2 O I I /4 /A A9 /{6 a A; a k III I I W/ J 17/447 Attorney Patented July 14, 1936 UNITED STATES PATENT OFFICE 1 Claim.

The present invention relates to a roller door latch and it is my object to provide a latch for a roller door, which automatically slides back, and is in out-of-the-way position, as the door is being opened. The advantage of this type of latch is, nothing will come in contact with it while an automobile is being driven in and out of a garage or the like, that is, nothing will catch on it and tend to injure the door.

Another important object of the invention resides in the provision of a latch of this nature which is simple in its construction, inexpensive to manufacture and install, thoroughly efficient and reliable in use and operation, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention consists in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a side elevation of the latch showing the same installed.

Figure 2 is a similar view showing the latch in another position, that is open position.

Figure 3 is a sectional view taken substantially on the line 3-3 of Figure 1.

Figure 4 is a section taken substantially on the line 4--4 of Figure 1.

Figure 5 is a detail elevation of one of the plates.

Figure 6 is a detail elevation showing the inner end of the latch.

Figure 7 is a perspective view showing a hook for the latch to drop in.

Referring to the drawings in detail, it will be seen that the numeral 5 denotes one side of a door frame and niuneral 6 denotes the door. A hook I is threadedly engaged in the side 5 as shown to advantage in Figure 3. On one side of the door 6 there is disposed a relatively short plate 8 and on the other side a relatively long plate 9. The plates 8 and 9 are provided with registering slots l0 terminating in depending notches llll, and of course, the door is provided with corresponding openings and notches. An elongated latch bar l0 has a notch l I at one end to engage the bolt or hook I as shown to advantage in Figure 1. At the other end this latch bar is provided with a square opening l2. Numeral M denotes a handle having a shank [5 to extend through the slots and openings in the plates and the door and is held in place by a suitable nut iii. A squared portion H is provided on the shank to fit in the square opening I 2. Numeral l9 denotes the guide on the plate 9 for limiting the swinging movement of the latch bar I 0'.

In Figure 1 I have shown the latch bar in locked position. Obviously the handle l4 may be swung so as to swing the bar upwardly out of engagement with the hook I and then the bar, the shank of the handle, and the handle itself may be lifted up and then the shank may be slid through the slots l0 into the other notches II to the out of the way position shown in full lines in Fi ure 2.

It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is:

A latch comprising an elongated plate, said plate having an elongated longitudinally extending slot therein having transversely extending end portions, an elongated latch bar having a keeper receiving notch in the outer end of its lower edge and a non-circular opening adjacent its inner end, a handle having a shank provided with a non-circular part fitting in the non-circular opening of the latch bar for oscillating the bar when the handle is turned and said shank having an elongated part of circular shape in cross section which passes through the slot, whereby when the last mentioned portion of the shank fits in either depending portion of the slot, sliding movement of the latch bar is prevented and a partially turning movement of the handle will raise the notched end of the latch bar, after which the handle is raised to place the shank in the horizontal part of the slot to permit sliding movement of the latch bar.

HENRY FLACKSBARTH.
